Description

Technical Field

[0001] The utility model relates to the technical field of mechanical clamps, in particular to a mechanical clamp which can be adapted to the processing of special-shaped parts. Background Art

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. In order to ensure the stability of the workpiece during machining, a fixing device is generally used to limit the position of the workpiece, and the shapes of the workpieces vary.

[0003] Some equipment on the market generally sets up a clamping mechanism. The staff first places the special-shaped workpiece to be clamped between two clamping seats, and then controls the electric telescopic rod to work. The output end of the electric telescopic rod moves and drives multiple clamping rods to move toward each other through mechanical transmission. The clamping rod moves and contacts the outer wall of the special-shaped workpiece. The irregular outer wall of the special-shaped workpiece squeezes the clamping rod, and the clamping rod moves toward the inside of the clamping seat. At this time, the spring is squeezed by force. This structure is conducive to the rapid clamping operation of the special-shaped workpiece.

[0004] However, during actual use of the above-mentioned device, when the device clamps special-shaped parts with sharp corners, the sharp corners will squeeze the clamping rod, which will cause the clamping rod to deform during long-term clamping, making it impossible for the clamping device to clamp better; in view of this, we propose a mechanical clamp that can adapt to the processing of special-shaped parts.

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a mechanical clamp that can adapt to the processing of special-shaped parts, including a mounting seat 1, a slide groove 3 is opened on the upper surface of the mounting seat 1, a mounting member 2 is fixedly connected to the upper surface of the mounting seat 1, an electric telescopic rod 4 is arranged on one side of the mounting member 2, and a mounting plate 5 is fixedly connected to one end of the electric telescopic rod 4, and the mounting plate 5 is clamped in the slide groove 3, which can make the mounting plate 5 more stable when moving, and a clamping device is arranged on one side of the mounting plate 5, and the clamping device includes a clamping groove 6, a clamping block 7, a clamping member 8, a mounting groove 9 and a limit member 10.

[0024] In the embodiment of the utility model, a card slot 6 is provided on the upper surface of the mounting plate 5. The card slot 6 is convexly arranged. The card slot 6 is evenly distributed on the upper surface of the mounting plate 5 in a linear array. A card block 7 is clamped inside the card slot 6. The size of the card block 7 is adapted to the size of the card slot 6. A clamping member 8 is fixedly connected to one side of the card block 7 near the bottom. An inclined surface is arranged on the side of the clamping member 8 near the center of the mounting seat 1, and a rubber convex strip is arranged on the inclined surface. A small inclined surface is arranged on the side of the clamping member 8 near the mounting plate 5. There are two clamping members 8, and the two clamping members 8 are symmetrically arranged at the center of the mounting plate 5. The center of the clamping member 8 corresponds to the center of the card block 7. This allows the clamping member 8 to better clamp the special-shaped member, so that when the clamping member 8 clamps the special-shaped block with a sharp angle, the inclined surface arranged on the side of the clamping member 8 near the mounting plate 5 and the sharp angle One side fits together, which can effectively prevent the sharp corners of the special-shaped part from damaging the clamping part 8, and at the same time, the clamping part 8 can also clamp the special-shaped part well. A threaded hole 11 is provided on one side of the clamping part 8, and a double threaded rod 12 is threadedly connected inside the threaded hole 11. The center of the double threaded rod 12 corresponds to the center of the mounting plate 5, and the size of the double threaded rod 12 is adapted to the size of the threaded hole 11. A mounting groove 9 is provided on the upper surface of the mounting plate 5 near the slot 6. The mounting groove 9 is arranged in an I-shaped manner, and a limiting member 10 is clamped inside the mounting groove 9. The limiting member 10 is clamped inside the upper surface of the clamping block 7. This can enable the limiting member 10 to better limit the clamping block 7 inside the slot 6, so that the clamping part 8 can be well installed on one side of the mounting plate 5, which allows the electric telescopic rod 4 to extend and push the mounting plate 5 to control the clamping part 8 to clamp the special-shaped part.

[0025] When the clamping member 8 is in the state of being pressed against the support 10, the clamping member 8 is pressed against the support 10, and the support 10 is pressed against the support 10, so that the clamping member 8 is in the state of being pressed against the support 10.

[0026] Furthermore, after the clamping member 8 clamps the special-shaped part, the double-threaded rod 12 can be rotated, which causes the double-threaded rod 12 to rotate inside the threaded hole 11, allowing the two clamping members 8 to move toward the center of the mounting plate 5, so that the clamping member 8 can clamp the special-shaped part more firmly, and a placement groove is provided at the center of the double-threaded rod 12, which can allow the sharp corners of the special-shaped part to be just stuck in, so that the special-shaped part can be clamped more stably.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
